Richmond PROG50-40N RH67 PDV

This site computed the 245 therms figure; the registry does not list it. It combines this model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. The UEF of 0.69 comes from the DOE CCD, retrieved 2026-09-19. Among the 414 gas tank models at that pattern, this unit ranks 130th lowest for energy use. The figure applies only at the federal test's daily draw. Energy use in any particular home is not available here, because the registry records no household data. The method behind the annual energy and cost figures sets out each input and how the two are combined.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 82 gallons. Its rated volume is 47 gallons. Both are registry values measured under test conditions. They describe capacity at the test, not the demand of a specific home. Suppose a home's peak-hour hot-water need is above 82 gallons. Then this unit does not match that load, and the 245 therms figure would not describe its use either. To check other gas tank models tested at the same pattern, use the same-class replacement search by model number.

Running cost is not written in this text, because it depends on your state's average residential gas price. The page applies that price to the 245 therms figure at the high draw pattern, using your ZIP. At any single gas price, the 15 therms gap below the 260 therms class median carries into cost at the same rate. The size of that gap in money is not available until your rate is known. The cost calculator for your own ZIP shows the result. The installed-cost block on this page is separate: it is a modeled range with its own source and date, not a quote.
